Effective Field Theory for Chaotic CFTs [PDF]

Journal of High Energy Physics, 2018
We derive an effective field theory for general chaotic two-dimensional conformal field theories with a large central charge. The theory is a specific and calculable instance of a more general framework recently proposed in [1].

Extended Effective Field Theory of Inflation [PDF]

Journal of High Energy Physics, 2018
We present a general framework where the effective field theory of single field inflation is extended by the inclusion of operators with mass dimension 3 and 4 in the unitary gauge.

Effective Field Theory for Inflation [PDF]

Physical Review D, 2008
The methods of effective field theory are used to study generic theories of inflation with a single inflaton field. For scalar modes, the leading corrections to the ${\cal R}$ correlation function are found to be purely of the $k$-inflation type.

A Lagrangian effective field theory [PDF]

Journal of Cosmology and Astroparticle Physics, 2015
We have continued the development of Lagrangian, cosmological perturbation theory for the low-order correlators of the matter density field. We provide a new route to understanding how the effective field theory (EFT) of large-scale structure can be ...

Effective field theory of 3He [PDF]

Few-Body Systems, 2010
3He and the triton are studied as three-body bound states in the effective field theory without pions. We study 3He using the set of integral equations developed by Kok et al. which includes the full off-shell T-matrix for the Coulomb interaction between

The Effective Field Theory of Inflation [PDF]

Journal of High Energy Physics, 2008
We study the effective field theory of inflation, i.e. the most general theory describing the fluctuations around a quasi de Sitter background, in the case of single field models. The scalar mode can be eaten by the metric by going to unitary gauge.

The Hypertriton in Effective Field Theory [PDF]

Nuclear Physics A, 2001
Doublet Lambda d scattering and the hypertriton are studied in the framework of an effective field theory for large scattering lengths. As in the triton case, consistent renormalization requires a one-parameter three-body force at leading order whose ...

Effective Field Theory of Cosmological Perturbations [PDF]

Classical and Quantum Gravity, 2013
The effective field theory of cosmological perturbations stems from considering a cosmological background solution as a state displaying spontaneous breaking of time translations and (adiabatic) perturbations as the related Nambu-Goldstone modes.
